The merchant should generate upiRequestId following these criterias:

• upiRequestId should be an alphanumeric 35 length string.

• It should start with a 3 character prefix which is given by NPCI for every handle. AXB, YJP and RBA are the prefixes for Axis Bank, Yes Bank and Rbl bank respectively. Example: "AXBfcd764aeab2a4bd195b25d652c1887f7" where AXB is the prefix.
